i'm working on swirl flow estimation, so i would like to estimate flow parameters such as angular velocity of the flow using optical flow methods. now i have the map velocity of the movement but i could not figure out how to estimate the angular velocity of the flow

Are you using the Computer Vision System Toolbox to do the optical flow? http://www.mathworks.com/help/vision/tracking-and-motion-estimation.html I think that's the first step. After that you'd have to write some custom code. I'm sure it's not a trivial 5 minute job, so I'm not going to do it for you. Good luck.
